v SPECIFICATION forming part of Letters Patent No. 413,629, dated October 22, 1889.

i Application filed April 10, 1889. Serial No. 306,695- (No model.)

To all whom it 11mg concern:

nectady and State of NewYork, have invented a certain new and useful Improvement in Machines for Covering Wire, of which the following is a specification. v

My invention relates particularly to that class of thread-winders for windin g thread or other material upon a wire wherein the supply-bobbin has a'motion of revolution around the wire to be covered, and also a motion of rotation on its own axis; and the main object of my invention is to enable a high speed to be maintained without exerting undue or uneven tension on the thread, whereby rapid. winding is effected without danger of breaking the threadduring the winding operation.

I accomplish this object by providing a guide for the supply-bobbin in its revolution around a rolling contact, whereby the friction on the axis of the spool is reduced'to a minimum I and the spool is permitted torotate at a high: I rate of speed without danger ofbreaking the thread. I further aid theattainment of the object stated. by providing a counterbalanceweight equal to the' averagelweight of the supply-bobbin located diametrically opposite the supply-bobbin, wherebythe vibrations due to thecentrifugal force of the bobbin in l. its revolution around the central spindle are neutralizedland the machine caused to run steadily and-evenly.-

- My invention is illustrated inthe accoml panying drawings, in which Figure 1 is a perspective view of my improved thread-winder; Fig.2, a vertical section and partial elevation thereof, and Fig. 3

' I shows the bearings of the spindle of the spool at its upper end.

A is a hollow spindle, supported in any suitable manner and driven by the pulley B and driving-band O, or in any other suit-able manner. Fed through the hollow spindle is the wire D to be covered, the feed. being'ef-. fected by any suitable feeding device, and

the speed of .feed. regulated to thesize of covering material 1 and number of revolutions of the supply-bobbin, as is well under- Be it known that I, WILLIAM A. PHILLIPS, asubject of the Queenof Great Britain, residing at Schenectady, in the county of Selle-'1 stood.

The supply-bobbin E is guided in its revolution around the central spindle by means of the guide-rings F, one of which is preferably located at each end of the bobbin. Each .of fthese'guide-rings is preferably a flat ring, as shown, free to rotate, and is centered with relation to the spindle A by. means of the axis G of the bobbin, and the weight H in contact with its inner periphery at points preferably diametrically opposite.

' Carried by the spindle A, preferably at each 7 of the spindle of'the bobbin. This V-shaped recess is just deep enough to hold the spindle of'the bobbin in contact with the inner periphery of the upper guide-ring and not per- 'rnitit to fall away therefrom. The lower end of the spindle is alsoheld in contact with the inner periphery of'the lower guide-ring by the lower arm I.

. The bobbin is inserted in place by passing the lower end of its spindle into its bearing between the lower arm I and lower ring F. Then the upper. guide-ring is raised sufliciently to permit the upper end of the spindle to be placed in the V-shaped recess of the upper arm I. The upper guide-ring is then restored to its position on the arm I, and the pivoted slide I, provided with slot 1, is brought into "position over the top of the guide-ring, the spindle of the spool entering the slot of the slide I. By this arrangement the operation of placing and removing the supply-bobbin is very much simplified, and the slide I holds the guide-ring in place, yet leaving it possible to readily remove it when desired. The roller H may be grooved, as shown, and the guide-ring entered in the groove. This will retain the guide-ring in pcsition at the end opposite the spindle of the supply-bobbin.

The rotation of the bobbin on its own axis is effected by the tension of the thread unwound by the revolution of the bobbin around the central spindle. Any suitable thread-guides maybe used to guide the covering material from the supply-bobbin to the wire being covered, and the guides used may exert a tension on the thread. I have shown the guides K, L, and M for such purpose. The rings F being free to rotate and the axis of the bobbin bearing against each of them at only one point, -it will be seen that the friction on the axis of the bobbin is inconsiderable. Diametrically opposite the arm I, at each end of the bobbin, is another arm 0, preferably formed in one piece with said arm I, as shown. Upon this arm 0 is mounted the weight H, preferably in the form of a roller, mounted on a fixed stud Q. This weight is about equal to the average weight of the supply-bobbin where only one weight is used;

but when two are used, as shown, one for each end of the supply-bobbin, each will be about half the average weight of the supply-bobbin. The chief function of the weight is to counteract the tendency of the centrifugal motion of the supply-bobbin to jar the machine; but it also serves, as before stated, to aid in centering and securing the ring F in place, and that it may oppose no resistance to said ring in its rotation is the object of loosely mounting it on the stud Q, whereby a rolling friction is obtained between the ring and weight.

It will be seen that by the use of the devices just described the vibratoryeffects set up by the centrifugal force of the revolving spool are rendered nugatory and the friction on the axis of the spool reduced to a minimum, whereby, on the whole, a machine is produced which may be run at a highIspeed, evenly and without jar, and in which the tension on the thread is slight and the danger of its breaking therefore small.

What I claim is 1.
